This invention relates to a cleaning and: scouring implement; and more particularly,

while water and a proper detergent is applied.

The device can readily be used where greater friction is necessary and in connection with abrasives, such as sandpaper, without substantial modification, where, for instance, it

' is desired to entirely remove the paint or finish.

The object of the invention is to provide a plied with case.

The invention consistsin the novel con-'- struction, arrangement and combinations of parts as hereinafter more specifically described and claimed.

tion on line 22 of Figure 1;

Figure 3 is a fragmentary vertical longitudinal cross section through the air supply conduit;

V Figure 5 is a vertical transverse cross section taken on line 5-5 of Figure 1; and

the housing is provided with a cylindrical chamber 8 in which slides a i931. Serial No. 535,040.

flanges are secured in abutment by bolts 4.

Each of the parts of the housing 1 and 2 are V provided with centrally positioned aligned bearings 5 for a shaft 7. Part 2 of piston 9 having a suitable packing ring 10. The piston 9 slides upon a centrally positioned rod 11, and the rear and open end of the chamber 8 is adapted to be closed by a handle 14 having an enlarged disc part 1-1 threaded r01 mate with the threads 15 to secure the handle 14 with relation to the member 2. Handle 14 is provided with a central. chamber 16 into which guide rod 11 extends and a spring 18 is positioned in this chamber so as to bear against the pistou9. The rod 11 is positioned centrally of chamber 8 by a seat 17 in handle 14.

A conduit 19 is provided through housing members 1 and 2 and through an extension nozzle8 provided on housing 1, this conduit Two sheets of drawings accompany thls.

19 connecting at the rear with a pipe 20, controlled as by valve 21, and is adapted to re 'ceive water from any suitable source through flexible tubing connected with pipe 20.

' A turbin'ewheel 22 is fixedly secured to shaft 7 being provided with blades 23 and compressed air is conveyed to this turbine wheel for driving the same through a conp 1 eter and at its forward end adjacent turbine 'l' i Figure 4 is a transverse cross section r through the nozzle on line 4-4 of Figure 1;

wheel -22 is arranged to communicate simultaneously with two of the blades 23, as is well illustrated in Figure 2. On the exhaust side of these two blades is a reversal condult 26 shown attached as by screws 26, 35 which" has a progressivelyexpanding bore receivingthe exhaust air from the two blades, andcommunicating at its posterior end with four of the turbine blades 28, delivering the residual energy of the exhaust to these 'four blades simultaneously,, thus leading the compressed air through the turbine twice in tWo stages of expansion.

llhe compressed air pipe 25 is provided at the endofhousing 2 with a by-pass pipe .30 controlled as by valve31, which pipe discharges between the disc of handle 14 and piston 9, thus impelling piston 9 forwardly withinrchamber 8, which chamber is adapted to receive a liquid detergent, such as soap.

The chamber 8 communicates by'passage 33' with nozzle 8 and discharges at the end of saidnoZZle adjacent the discharge of con- V duit '19, conveying water. r is 1 The chamber 8 can be refilled with soap,

as though hole 35, normally closed by bolt 36. On the forward end'oi shaft 7 is secured a sleeve 38 as by screw 39 whichsleeve38 is provided at its forward end with a bayonet slot 41.

V 43 and a stud 44 provided with a pin 45 isadapted to be secured in interlocked posi- 1' tion withsleeve 38 "to bewrotated by, shaft 7 and the nozzle 8 is of a length and so positioned as to discharge water orwater and soap upon the expanded bristles of the'brush when the same is pressed 1 for cleaning purposes.

against a 7 surface A brush 42 having bristles for applying a fluid under pressureto the other end of the cylinder whereby the piston is advanced in the cylinderto supply a detergent to the brush from the cylinder.

2. The structure of claim 1, with a second liquid supplying conduit carried bythe hous ing and discharging adjacent the discharge end of the first conduit.

In testimony whereofwe alfix our signatures. V

' Where it is desired to apply greater fric- I 7 tionthan can be securedwith a brush, a

{disc 47 is pro-videdhaving a similar stud 44 with pin 45, butadapted to be covered a band 48 to disc 47. p

In operation, the opening of valve 21 will c.

- permit the discharge of water through noz-Q zle 8' without the rotation of brush42. If

it. is desired 'to rota'te" brush 42 withr only the water being supplied, the valve 31 will be closed and valve 25'opened to supply compressed air to turbine wheel 22 and rotating brush 42. If it bedesired to supply a de tergen't with the water, valve 31 will be opened thereby supplying compressedair behind the piston .,9 and thus forcing soap through conduit 33 tor-be discharged adjacent "the water from the end of nozzle 8'. r

-The 'implement can be conveniently hail-,
